- Do not substitute for other clonidine products on a mg-per-mg basis, because of differing pharmacokinetic profiles
- Doses higher than 0.4 mg/day have not been evaluated and therefore not recommended.
- Since it has not been systematically evaluated for long-term maintenance treatment, physicians should periodically assess usefulness if prescribed for extended periods.
